Hello!
It’s a convenience array where all the related data posted can be retrieved. PHP is just giving you a shortcut so you don’t have to parse the body of the request that was sent to the server.
When you submit data or send data through AJAX, the server (in whichever language it’s written) has to parse the contents and then deliver them to the consumer (the scripts, classes, controllers, etc.). In this case, PHP handles the request data, parses the contents sent by the client (your browser or AJAX) and conveniently stores this data on the $_POST array (only if the method used was POST). There’s also the $_REQUEST array that has all the data sent, regardless of the method (post, get, put, delete, etc.).
Of course, that’s a simplification, but it’s essentially what’s doing. Read online what’s the definition of a client, a server and what other methods exists besides post.
Does it help 
?
